Abstract
A method is presented that enhances the survivability of system software components, even in the event of catastrophic failure of the computing element on which they reside. In particular, the combination of a distributed operating system (Non Stop Clusters) and a fault-tolerant interconnect (ServerNet) provides an environment conducive to posthumous recovery strategies that have been unavailable in previous distributed computing environments. The specific strategy outlined here is called resource harvesting, and involves a novel approach that retrieve critical data structures of memory from a failed computing element for reconstruction on a non-failed computing element, allowing such critical data structures to continue with their original function.
